What has this got to do with the original quote? The quote was claiming, truthfully or not, that when one is first presented with a certain type of problem, one is dumbfounded for a period of time. And of course the problem is solvable, and of course even without calculating it you can get a rough picture of the range the answer is in, and with a certain amount of practice one can avoid the dumbfoundedness altogether and move on to solving the problem, and that is a fine response to give to the original quote, but it has no relevance to what I was saying.

All I was saying is that it is an invalid objection to object to the quote based on the fact that with a certain technique the specific example given by the quote can be avoided, as that example could have easily been replaced by a similar example which that technique does not solve. I was talking about that specific objection I was not saying the quote is perfect, or even that it is entirely right. You may raise these other objections to it. But the specific objection that Jayson_Virissimo raised happens to be entirely invalid.
